What Special Requirements Does VSP Place on Laminated Trays?
VSP vacuum-draws a heated skin film over food and tray. The tray lamination can be a standard EVOH film — the key is an easy-peel PET skin cover film for clean tearing and separation.
Solution Essentials
Standard laminate works
The tray lamination can be a regular EVOH film — no dedicated low-peel grade needed.
Vacuum-proof
No delamination at -0.9 bar draw.
Easy-peel skin film
Pick an easy-peel PET skin cover film so it tears off and separates cleanly from the tray.
Premium display
Skin-pack effect lifts the shelf image of premium meats.
VSP Structure Recommendations
Skin cover film and tray lamination must be selected as a pair.
| Vacuum level | -0.85 to -0.95 bar |
|---|---|
| Tray lamination | Standard EVOH lamination film |
| Skin cover film | Easy-peel PET skin film |
| Service temp. | Frozen and chilled |
| Release residue | <2% area (measured) |
| Validation | Skin conformance + release + drop test |
VSP FAQ
Can the tray lamination be a standard film?
Yes — a standard EVOH lamination film works; the key is an easy-peel PET skin cover film for clean tearing and separation.
Will vacuum pull the laminate off?
Qualified laminates hold at -0.9 bar; verify before supply.
How much more does a VSP tray cost?
About 10–20% more, easily absorbed in premium categories (high-end meat, seafood).
